With those parts don't just get the machine machining done. Go full out race prep on the block. Make sure it get totally stress relieved. Those parts are really nice to have, but you're polishing a turd when dealing with a stock block no matter how much money you throw at it. Better make sure your tune is up to par, also.

What are your power goals with the car? What kind of driving will it see? How often? Stock stroke? Srtoker? You can use box stock Twisted Wedge heads on a stock shortblock. You have to clay the pistons if you're going to be .226 or over in duration to ensure whether or not your cam will clear. Power band will not solely depend on which cam and heads you're using, but intake as well. If you want most of the power down low a good aftermarket street intake (or dual plane if you're carbed) will do. Race intakes where they make power well above your rev limiter, like the Victor series or Track Heat intakes, will take away from your low end.

 

im shooting for only 350 HP for right now but im going to supercharge it later on, im going with a stock stroke,and its going to be daily drivin....this is whats is going in... https://www.tamparacing.com/forums/s...d.php?t=223790

 

If your staying stock cubes... dont expect anything close to 350rwhp....

What rollers are you planning on going with? That has alot to do with final lift and P to V clearance. And like John stated, the twisted wedge refers to the arrangment of the valves in the head. Stock valve relief pistons will be fine...

Let us know how it comes along..

 

I just finished installing a set of TFS Twisted Wedge heads, TFS Track Heat intake and a TFS Stage 2 camshaft in a 91 LX with a stock bottom end. It ended up putting 304HP to the rear wheels which is about 360HP at the flywheel.

Needless to say there wasn't any clearance problems at all.
